Product Description:

Bosch Rexroth Indramat manufactures the MAC112D-0-ED-4-C/130-B-0/WI522LV as part of the MAC AC Servo Motors series. This unit is a motor for analog drives that converts command voltages from legacy drive amplifiers into controlled electromechanical motion for positioning tables, packaging lines, or tool spindles in industrial automation. By integrating the windings, rotor, and feedback devices into one enclosure, the motor supports rapid acceleration and repeatable speed regulation in tightly coupled motion loops.

The motor size 112 establishes the stator frame envelope, while the length code D provides a deeper active stack for higher continuous torque without increasing the diameter. Precise mechanical centering is achieved with a 130 mm pilot, allowing rigid coupling to gearboxes or machine plates. Heat generated in the windings is removed through natural convection, so no external blower or liquid circuit is required. The armature uses winding code ED, which corresponds to resistance and inductance values matched to standard Indramat analog amplifiers. A rated speed of 3000 rpm can be reached under nominal voltage, giving the axis enough overhead for fast traverse and quick reversal.

Power enters the machine through a connector located on side B, which can simplify cable routing when the motor is mounted with the shaft facing forward. Position feedback is provided by an incremental encoder installed with standard mounting hardware. The wiring harness also carries tacho signals generated at 3 V/1000 rpm for analog speed loops that rely on real-time velocity voltage. The feedback arrangement supports speed and position monitoring for legacy control systems. Tacho quality is standard, and the assembly is supplied without a blocking brake, so holding torque must be provided externally when needed.
